Only a very small number of machines remain that rely on
traditional board files with the ATAGS boot data instead
of devicetree, and we have not accepted new ones for
a decade.

Most of the remaining ones are on their way out of the
kernel, but the Kconfig option that controls ATAGS
is still enabled by default.

To reflect the actual status of ATAGS support and alert
the remaining users of upstream and out-of-tree platforms
with this, chanyge it to being default-disabled and
add a dependency on CONFIG_EXPERT.

The board specific defconfig files that rely on ATAGS
are changed to turn on both EXPERT and ATAGS if they
were not doing thath already, and the ones that explicitly
turned it off before no longer need to.
